Transforming everyday appliances into Doom gaming machines is something of a sport. We've already witnessed the FPS game running on everything from a digital camera display to a restaurant order system, and it even runs on holographic displays. Thanks to developers over at Adafruit, the id Software classic is now playable on a gaming PC that's smaller than a credit card, providing you're not prone to hand cramps.
The Adafruit QT Py Doom playing device (codename PINKY) uses a ESP32 Pico v3 02 SoC at its core, complete with a dual Tensilica 240MHz CPU and 2MB PSRAM. The device meets the classic shooter's system requirements by also wielding a 1.3 inch TFT display, and a bunch of tiny micro switches to boot.
The device uses Retro-Go port of Prboom, an overhauled version of the original Doom engine. While getting the game onto unconventional appliances usually requires some tinkering, Adafruit says the DOS shooter "pretty much just worked" after simply loading the shareware DOOM1.WAD file from an SD card.
